AUGUST E. ROEVEB, OF BROOKLYN, NEW YORK.

POWER-TBANSMITTING DEVICE.

Specification of Letters Patent.

Patented Nov. *7, 1.916.

Application led September 30, 1915. Serial No. 53,246.

To all whom t may concern Be it known that I, AUGUST E. ROEVER, a citizen of the United States, residing at Brooklyn, in the county ofKings and State of New York, have invented certain new and useful- Improvements in Power-Transmitting Devices, of which the following is a specification.

This invention relates to improvements in power transmitting devices, the object of the invention. being to provide a device of 'this character adapted to coperate with the motor-driven fan of a vacuum cleaner whereby the motor may be utilized for the performance of other work, such as running a sewing machine or a fan, or for any other purposes for which it may be desired to use the motor.

In the drawings accompanying and forming part of this specification, Figure 1 is a front view of my improved power-transmitting attachment; Fig. 2 is a side elevation thereof; Fig. 3 is a side elevation of the device, partly in section, with the motor and vacuum cleaner fan attached thereto; Fig. 4 is a sectional view taken on line 4 4, Fig. 3, looking in the direction of the arrows; Fig. 5 is a front view illustrating a modified form of the device; Fig. 6 is an enlarged fragmentary view illustrating the preferred manner of mounting the improved friction disk and its connection with a pulley for transmitting rotary motion from the motor; and Fig. 7 illustrates a form of vacuum cleaner with the motor and fan of which this improved device is adapted to be used.

Similar characters of reference indicate` corresponding parts in the different figures of the drawings. v

The vacuum cleaner shown in Fig. 7 comprises two main portions or casing members 2 and 4, in the upper one 4 of which is mounted an electric motor carrying a fan,

mounted on a shaft extending from said motor below the same, said fan projecting beyond the edge of the casing 4. The lower shell or casing member 2 carries a suction nozzle for contact with the surface to be cleaned., a fan chamber in which the fan is housed when the casing members are secured together, and a passageway for conveying the dust and dirt from the fan chamber into the receptacle or bag 3. The casing members 2 and 4 are adapted to be quickly and easily attached together and detached, and for this purpose the upper member 4 is provided at its lower edge with radially extending lugs 5, see Fig. 1, having open slots adapted to engage set screws 6 threaded into the lower casing member 2, whereby the casing members are in intimate contact when the vacuum cleaner is in operation, but by merely releasing the set screws and giving the upper member 4 a slight circumferential twist the members 2 and 4 are separated one from the other.

The improved device in the present instance comprises a frame formed of two upright plates 7 and 8, spaced apart by sleeves 12 at their four corners and secured together by bolts passing through said sleeves and screwed into one of the plates. For the purpose of adding stability to the device, the plates 7 and 8 may have their lower sides turned at right angles, as at 9, Figs. 2 and 3, and these flange portions 9 `may be provided with holes 10 for permit-y ting the device to be bolted to a wooden platform or other support if necessary. Reinforcing webs 11 may also be formed between the upright portions of the plates and the iianges 9 to afford greater stability if desired.

In the preferred form of my improve-y ment, in one of the upright plates, as 8, is mounted in any Suitable manner a sleeve 15` see Fig. 6, through which extends a stud shaft 14 having an enlarged head in the form of a disk 13 which is countersunk into the front face of the projecting drum portion 27 of the disk 18 and secured thereto, as for instance by being wedged therein, so as to rotate therewith, said shaft extending throughy the sleeve and projecting a suiiicient distance from the plate 8 for carrying a pulley 16, which may be fastened on said shaft by means of a pin 17 passing through the hub of the pulley and through the shaft. The clutch member or disk 18 and its drum portion 27, to which it is secured in any suitable way, thus rotate loosely on said sleeve, thereby rotating the shaft 14 and pulley 16, a suitable washer 19 being interposed between the clutch member 18 and the plate S. The plate S is also provided with an opening above the center thereof to aiford a bearing for a shaft :2O carrying at one end thereof a double pulley 21, which is connected by a belt 25 with the pulley 16, said shaft having a bearing at its opposite end in the front plate 7 cf the frame. The plate 7 is provided centrally thereof with an opening 22 of a diameter sufliciently large to permit the passage therethrough of the fan carried on the motor shaft, and this plate is also provided with threaded openings 9.3 for the reception of the set screws 6 for seein'- ing the casing member -i to the device in the same manner as it is secured to the casing member 2 of the vacuum cleaner.

My improv-ed clutch member may be formed in a number of different ways, and 1 have shown herein two forms thereof. 1n the form shown in Figs. 1 to fl this clutch member comprises a dish 18 having a projecting drum portion 27 provided with radially disposed grooves Qt adapted to register with and Corresponding in shape and depth to the blades of the fan carried on the motor shaft. ln this form of the device it will be obvious that by securing the motor casing -i to the plate 7, with the fan blades within the grooves 2-1, the rotation of the motor will be transmitted through the fan, which forms one member of the clutch, to the pulley 16, and from thence, by means of the belt Q5, to the double pulley, and may thus be used for any purpose for which it may be desired to use a motor. instead of the double pulley Q1, a single pulley may be used and the shaft 2O provided with a squared end for the reception of a fan for agitating the atmosphere and cooling the room.

The improved clutch member may consist merely of a friction plate or dish, which. may consist of a rigid plate provided on its face with a layer of some suitable material for creating friction between the fan blades and the dish, so that when the disk is brought into close Contact with the fan it will be rotated therewith owing to the frictional contact of the fanblades with the material on the plate or disk, or the disk may consist of some flexible material, such for instance as leather Q6, as shown in Fig. 5, and which dish is xed to the shaft 1% to rotate therewith and. by reason of its flexibility, the disk will be sucked, on the rotation of the fan, into engagement with the fan blades to be rotated thereby. Of course the shaft 1-1@ may have a slight sliding movement toward the fan when the leather dish is sucked toward it, thereby to insure a firmer cont-act or grip of the fan blades on the leather dish. it has been found in practice that the leather disk, on the stoppage of the fan, practically frees itself from the fan, but on the next rotation of the fan the engagement is again made and the shaft 1i and its pulleyrotated in the manner hereinbefore described.

lVhile I have shown in Fig. 6 what regard as the preferred manner of mounting the dish 18 and pulley 16 on the plate 8, it will be understood that this may be accomplished in a number of different ways. F or instance, the sleeve 13 may be entirely dispensed with and the shaft 1st mounted directly in the plate and secured to the disk in any suitable manner. This and many other details of construction may bemore or less varied without departing from the spirit and scope of this invention, andthe improvement used in connection with any motor having a fan or rotating blades suitably located for this purpose.
